INCUBATOR.

Specification of Letters Patent.

Patented Oct. 22, 1907'.

Application iiled May 10, 1907. Serial No. 372,985.

To all Awhom 'it may concern:

Be it known that l, A-Lross MU slot, a subject oi the Emperor oi' Austria, residing in Tabor, `Kingdom ol Bohemia, Austrian Empire, have invented a new and usel'ul Incubator', ol which the iollowing is a specification.

illy invention relates to improvements in hatching ovens, with the objects oi a cheap and well working y hatching device with a complete and reliable regulation oi' temperature and regulation ol air, by heating it directly with a small petroleum lamp, or the like. 1 attain these objects by the device illustrated as an eX- ample in the accompanying drawing, in which-A Figure l, is a vertical section of the oven, and Fig. 2 another vertical section oi the same oven, being at right angles to the former one.

Inside a double box having the space between its walls l and 2 filled with cheap insulation (chal't' or the like), is interposed an oven, which consists of a suitably shaped body 4, 5 ol' zinc or the like, with an air-space between its side-walls Il and the bottom 5 and between said box. This air-space between the outward double box and the oven, as shown in cross section in Fig. 1, is heated directly by a small petroleum lamp 10 or the like, the cylinder of which reaches through an opening 25 into said air cushion, said opening 25 as Well as other openings 2l being arranged for the circulation ol air and lor the removal of the products ol ignition. The apparatus may be provided with supports 2G at convenience. I

The interior of theI oven 4, 5 is accessible by its door` 24, and is ventilated by openings S and Sl and a chim ney 1l, 12, which can be more or less closed by a light disk 15 of aluminium for instance. Disk l5 is held normally closed by a steel band, 1G. Opening the chimney 12 is preferably attained by an electromagnet 14 oi which said band 16 forms the armature, itscircuit having its source in a battery 19 or the like. ln the same circuit is also a contactsthermometer 13 inside the oven, and a controlling button 17 outside on the top. The valve l5 may also be withdrawn, for opening the chimney, in turning the small lever or pawl 18 with the lingers, while by the electric device the opening of the chimney proceeds automatically. 1f the heat near the eggs reaches a given limit oi degrees, the contact-thermometer 13 closes the circuit, the electromagnet 14 attracts the band 16 and by this opens the ehimn ey 12, and the inside ol' the oven becomes cooled by the draft oi atmospheric air, which enters freely through the openings S, 9.

20 is an ordinary thermometer.

Pressing the con-trolling contact-button 1'7 with the finger will show at any moment whether the circuit is in order.

The eggs repose in the oven preferably upon perlorated plates 7, which may bewithdrawn or put in the oven through the door 24. Vessels with water 22, may be provided upon the bottom 5 of the oven, to produce the necessary moisture inside th e oven.

l am aware that, prior to my invention, hatching ovens have been made. I therefore do not claim such a combination broadly; but

l claim:

l. An incubator comprising a casing having double walls having heat insulating material therebetween, a metallic box supported in said casing so as to leave a space between two oi its sides and its bottom and said casing, means for heating the air in said space, said casing having openings in its top and betteln, means ior regulating the temperature automatically and mechanically and means for supplying moisture to the box.

2. An incubator comprising a casing, a metallic hatchingbox supported in said casing so as to leave a space between two of its sides and its bottom and the casing, means for heating' said space, said box having an opening leading to the atmosphere, a chimney connected with the box, a valve normally closing said chimney, an electric circuit, an electro-magnet therein, a steel hand carrying the valve and acting as the armature for the electro-magnet and a thermostat in said box and forming part of the electric circuit.

In testimony whereof l nfx my signature in presence of two witnesses.
